about ADV7511 and ZC706

Hi,

Can you give us more details about what is not working?

How did you program the FPGA? How did you build the HDL and no-OS projects?

Did you go through these guides? https://wiki.analog.com/resources/fpga/no-os_make/software_setup  https://analogdevicesinc.github.io/hdl/user_guide/build_hdl.html 

Best regards,
Iulia

These pictures are the result of the making the no-os project.then program the FPGA by 'make run'. I found that the function 'no_os_init()' enters error, return -22.  The PL logic no error when making it.

Hi MarkMa ,

You could activate debug messages so more information is displayed in the terminal. For this, replace NO_OS_LOG_INFO with NO_OS_LOG_DEBUG in:

https://github.com/analogdevicesinc/no-OS/blob/c62fe1a06b95dea4936f71c041e37be3e5a3c33d/include/no_os_print_log.h#L55

Another option would be to debug the application using Vitis. For this, run the following command to open the project in the IDE:

make sdkopen

More info regarding the project can be found here:

I found that the device_id is 0xf8f00000. Is it OK?

Hi MarkMa ,

The no-OS project uses the library mentioned here: github.com/.../README

There is a public Linux driver for the ADRV7511. You can get the information from there. As you can see, the CHIP ID of the device is 0x7511:

https://github.com/analogdevicesinc/linux/blob/81fb3d4f0289373257b36a22a29006c252bdfd79/drivers/gpu/drm/bridge/adv7511/adv7511_drv.c#L79C32-L79C42

You can also find more information regarding the part in other EZ threads:

In main.c, the 'device_id' is not initialized actually。why？

int32_t ret;

adv7511_extra_i2c_init.device_id = XPAR_AXI_IIC_MAIN_DEVICE_ID;
adv7511_extra_i2c_init.type = IIC_PL;
adv7511_i2c_init.max_speed_hz = 400000;
adv7511_i2c_init.slave_address = 0x39;
adv7511_i2c_init.platform_ops = &xil_i2c_ops;
adv7511_i2c_init.extra = &adv7511_extra_i2c_init;
#if defined(_XPARAMETERS_PS_H_)

The device_id should be the ID of IIC interface, It is not the device_id of ADV7511 chip. 

You are right. Adding the following line solves the problem:

adv7511_i2c_init.device_id = 0;

We'll update the project accordingly.

Thanks,

George

There are some messages in the terminal.But the HDMI can not run.There are no pictures on my monitor.
